Ap Chemistry 1997 Free Response Answers
Hydrogen atoms in water molecules can form a strong bond a hydrogen bond with the nitrogen atom in the pyridine ring, allowing the pyridine molecules to be carried into solution. Benzene is not soluble in water because no hydrogen bonding is possible. Attractive forces among molecules of benzene and attractive forces among molecules of water are both stronger than the weaker attractive forces among molecules of benzene and water mixed together. One point is earned for recognizing that pyridine can form H-bonds with water. One point is earned for recognizing that benzene cannot form H-bonds with water. The normal boiling point of dimethyl ether is K, whereas the normal boiling point of ethanol is K. Account for the difference in boiling points. The intermolecular forces of attraction among molecules of dimethyl ether consist of London forces and weak dipole-dipole interactions. However, the intermolecular forces among molecules of ethanol include London forces, dipole-dipole interactions and hydrogen bonds.

The hydrogen bonds are particularly strong and are more difficult to overcome during the boiling process. Thus ethanol molecules must have greater average kinetic energy i. One point is earned for recognizing that ethanol molecules can form H-bonds , whereas dimethyl ether molecules do not form H-bonds among themselves. One point is earned for recognizing that, compared to the energy required to break the weaker intermolecular forces in liquid dimethyl ether, more energy is required to break the H-bonds in liquid ethanol, leading to a higher boiling point.

Account for the difference in melting points. In the solid phase, SO 2 consists of a crystal made of discrete molecules that are held together with London forces and dipole-dipole interactions. These forces are relatively weak and are easily overcome at a relatively low temperature, consistent with the low melting point of SO 2. In solid SiO 2 no discrete molecules of SiO 2 exist. Rather a network of Si atoms and O atoms are linked by covalent bonds, which are much stronger than typical intermolecular bonds. Only at high temperatures do the atoms in SiO 2 have sufficient energy to overcome the covalent bonds holding them together One point is earned for recognizing that sulfur dioxide is a molecular solid and that only weak London forces must be overcome in order for the molecules of SO 2 to slide past each other.

One point is earned for recognizing that SiO 2 is a covalent network solid and that strong covalent bonds must be overcome in order for SiO 2 to melt. Account for the difference in normal boiling points based on the types of intermolecular forces in the substances. The intermolecular forces in liquid Cl 2 are London dispersion forces, whereas the intermolecular forces in liquid HCl consist of not only London forces but also dipole-dipole interactions due to the polar nature of the HCl molecule. In general, dipole-dipole interactions can be quite strong and London forces can be relatively weak. But the cumulative effect of the London forces and the dipole-dipole interactions in liquid HCl is less than that of the London forces in Cl 2 , leading to a higher boiling point for Cl 2. One point is earned for recognizing that the London forces among molecules in liquid Cl 2 are stronger than the combination of London forces and dipole-dipole attractions among molecules of HCl.

The multiple-choice questions in Section I cover the breadth of the curriculum. Section II, the free-response part of the exam, includes three quantitative problems, one question on writing chemical reactions and predicting products, and two essays. One of the questions in Section II is based on laboratory; this question can either be a quantitative problem in Part A or an essay in Part B. There is no choice among the questions; all students must answer all six questions. Calculators are allowed on the free-response section for the first 55 minutes. During that time, students will work on three required problems. For the last 40 minutes, calculators must be put away as students work on the remaining free-response questions. For the first 55 minutes, any programmable or graphing calculator may be used, with a few exceptions, and students are not required to erase their calculator memories before and after the exam. Although most calculators are permitted on the free-response section, calculators may not be shared with other students and those with typewriter-style qwerty keyboards will not be permitted on any part of the exam.

II is not correct. In addition, there are proportionally more protons to electrons. This pulls the electrons even closer to the nucleus. And in Potassium, the outer shell electrons are a substantial distance from the nucleus. There are a greater number of protons than electrons; however, the large number of electrons dissipates the effect. This is in addition to Lithium being a much smaller neutral atom than Potassium because of the difference in the outer shells. This weakens the attraction per electron. Since the attraction is weaker, the electrons are farther from the nucleus. Since the attraction is stronger for Cl, the electrons are closer to the nucleus.

Distinguish genetic drift from gene flow in terms of how they occur and their implications for future genetic variation in a population. Genetic drift, defined as the process in which chance events cause unpredictable fluctuations in allele frequencies from one generation to the next, can increase or decrease variability within particularly small populations. Examples of genetic drift might include the founder effect, which consists of a select amount of individuals is separated from a larger population and eventually establishes a gene pool different from that of the source population, or the bottleneck effect, in which a severe drop in population size can leave some alleles overrepresented in survivors and others underrepresented.

In contrast, gene flow is the transfer of alleles into or out of a population due to the movement of fertile individuals on their gametes. Unlike the random favoring of traits that comes about through genetic drift, gene flow can transfer alleles that improve the ability of populations to adapt to local conditions, ultimately becoming a mechanism of natural selection. Adhering to the definition of natural selection, individuals with beneficial traits survive and reproduce more efficiently- thus increasing the flow of
